Product Description

Siemens 3SB5000-4HC01 Key Switch – 22 mm, 3 Positions I-O-II, Maintained

The Siemens 3SB5000-4HC01 is a 3-position key switch from the Siemens 3SB5 series, designed for industrial control panels, machine-control systems and automation applications. It features a 22 mm round plastic construction, I-O-II three-position configuration, maintained operation, key removal in both right and left positions, 2 × 50° operating angle and holder.

Its key-operated design provides controlled operator access and is particularly useful for machine functions where different operating states need to be selected and maintained.

3-Position Key Switch – I-O-II

The 3SB5000-4HC01 provides three defined operating positions:

I → O → II

This configuration allows one key switch to control or select between three different operating states.

Depending on the machine's control philosophy, the positions can represent:

• Mode I / OFF / Mode II
• Manual / OFF / Automatic
• Forward / OFF / Reverse
• Local / OFF / Remote
• Function I / Neutral / Function II
• Operating mode selection

The actual function of each position depends on the electrical control circuit and machine design.

Maintained Operation

The 3SB5000-4HC01 is maintained, meaning the selected position remains mechanically held until the operator turns the key to another position.

This makes it suitable for applications where a continuous operating-mode selection is required rather than a temporary command.

Typical applications include:

• Operating-mode selection
• Manual/automatic selection
• Local/remote selection
• Forward/reverse control
• Machine function selection
• Service-mode selection
• Control authorization

Key Removable in Both Positions

A major feature of the 3SB5000-4HC01 is that the key can be removed in both the right and left positions.

This provides flexibility when the key position is used as part of an operator authorization or machine-access procedure.

For example, the key can be removed when the switch is in either end position, depending on the machine-control arrangement.

Potential applications include:

• Authorized machine operation
• Maintenance access
• Service-mode control
• Restricted operating modes
• Machine authorization
• Operator access control

The exact safety or authorization function depends on the complete control-system design.

2 × 50° Operating Angle

The switch has 2 × 50° operating angles, providing a total three-position arrangement around the central position.

The operating sequence can be represented as:

I ← 50° → O ← 50° → II

This gives the operator clearly defined mechanical positions for selecting different machine operating states.

22 mm Round Plastic Design

The 3SB5000-4HC01 uses a 22 mm round plastic construction, making it suitable for standard industrial operator panels and control cabinets.

Its compact design allows installation alongside other Siemens 3SB5 components such as:

• Pushbuttons
• Illuminated pushbuttons
• Selector switches
• Indicator lights
• Emergency-stop devices
• Other operator-control components

Holder Included

The product is specified with holder, allowing the key switch to be integrated into compatible Siemens 3SB5 panel-control assemblies.

This makes it suitable for OEM control panels and standardized machine operator interfaces.

Applications

The Siemens 3SB5000-4HC01 can be used in:

• Industrial automation
• Machine control
• Motor-control systems
• Production machinery
• Packaging machinery
